Goblet cells are examples of what type of exocrine glands?

• A. Multicellular glands
• B. Holocrine glands
• C. Unicellular glands
• D. Endocrine glands

Answer: (C)

Verified step by step guidance

1. Understand the role of goblet cells: Goblet cells are specialized epithelial cells that secrete mucus to protect and lubricate surfaces in the respiratory and digestive tracts.
2. Identify the type of secretion: Goblet cells release their product directly onto the surface of the epithelium, which is characteristic of exocrine glands.
3. Differentiate between unicellular and multicellular glands: Unicellular glands consist of a single cell that performs the secretory function, while multicellular glands are composed of multiple cells.
4. Recognize that goblet cells are unicellular: Goblet cells are unique because they are single-celled glands that perform the function of secreting mucus, classifying them as unicellular exocrine glands.
5. Clarify the distinction from endocrine glands: Endocrine glands release hormones directly into the bloodstream, unlike goblet cells, which secrete mucus onto epithelial surfaces.
